Nyob rau hauv cov nqe lus ntawm raw cov ntaub ntawv, nws muaj cov nram qab no zoo: nce qhov ceev ntawm ntsuab lub cev thiab txo cov dej ntsiab lus thiab porosity. Cov hauv qab no yog cov ncauj lus kom ntxaws txog rau lub cev lub cev ntawm cov khoom siv alumina.
Nws tuaj yeem siv los ua catalyst thiab catalyst cab kuj hauv kev lag luam tshuaj chiv thiab petrochemical kev lag luam. Nws tuaj yeem siv ua desiccant rau roj thiab kua, defluorination tus neeg sawv cev rau dej haus, adsorbent rau roj purification, thiab lwm yam.
Lub cev muaj zog ntawm activated alumina spheres:
1. Lub kaum sab xis ntawm repose. Lub kaum sab xis ntawm repose ntawm alumina yog hais txog qhov inclination ntawm cov khoom siv ntuj tsim los ntawm cov txheej txheem du. Alumina nrog lub kaum sab xis loj yog qhov yooj yim thiab yooj yim rau yaj hauv electrolyte. Nws tuaj yeem npog lub plhaub ntawm lub tshuab electrolyte hauv cov txheej txheem ntawm electrochemical machining thiab ntau lawm, nrog me me ya poob.
2. A-Al2O3 cov ntsiab lus. Hauv alumina - Cov ntsiab lus ntawm Al2O3 qhia txog calcination degree ntawm alumina. Qhov siab dua qhov calcination degree, qhov siab dua cov ntsiab lus ntawm a -Al2O3. nrog rau - Nrog rau qhov nce ntawm Al2O3 cov ntsiab lus, hygroscopicity ntawm alumina ua phem. Yog li ntawd, alumina rau electrolysis yuav tsum muaj ib tug npaum li cas ntawm - Al2O3. Txawm li cas los xij, solubility ntawm a-Al2O3 hauv electrolyte yog phem dua li ntawm y-al2o3.
3. Tej qhov ntom ntom. Qhov ntau ntom ntawm activated alumina pob yog hais txog qhov hnyav ntawm ib chav tsev ntim ntawm cov khoom nyob rau hauv ib puag ncig ntuj. Feem ntau hais lus, alumina nrog tsawg bulk dens yog conducive rau kev sib cais ntawm electrolyte.
4. Particle loj. Qhov loj me me ntawm lub pob alumina yog hais txog nws qhov zoo. Qhov loj me me ntawm alumina yuav tsum tsim nyog.
5. Cov cheeb tsam tshwj xeeb. Qhov tshwj xeeb ntawm thaj chaw ntawm lub pob alumina yog hais txog tag nrho thaj chaw ntawm qhov sib npaug ntawm thaj chaw sab nrauv thiab sab hauv qhov pore nto ntawm cov khoom hauv ib chav tsev qhov hnyav. Qhov tshwj xeeb ntawm thaj chaw siab thiab lub pob qhib alumina muaj cov solubility zoo thiab kev ua haujlwm hauv electrolyte thiab yooj yim nqus dej noo.
6. Hnav coefficient. Qhov thiaj li -hu ua coefficient yog feem pua ntawm cov ntsiab lus hauv cov qauv tom qab lub pob alumina activated yog hauv av nyob rau hauv tej yam kev mob hauv lub txaj fluidized.
